The Fujitsu SET-ARTH45KHTA-HP is a high performance reverse cycle ducted air conditioning system designed for large homes and demanding installations that require long duct runs, stronger airflow, and higher static pressure. Compared to the standard ARTH45KHTA, the High Performance version is built to deliver stronger airflow and improved operation across larger or more complex ducted layouts. With 12.5kW cooling and 15.0kW heating capacity, this model is ideal for large living areas, open-plan homes, offices, and spaces around 55–90m² depending on insulation and layout. It is designed for installations where standard slimline or lower static systems may not provide enough airflow or duct pressure.

Key Features & Benefits

High Performance Static Pressure

The High Performance range is engineered for installations requiring stronger airflow and higher duct resistance, making it ideal for long duct runs, multiple outlets, and larger zoned systems. Fujitsu’s high static range supports static pressure from 60Pa up to 260Pa, helping maintain more consistent airflow throughout the home.

Strong Airflow Output

The system delivers approximately 903 litres per second of airflow on high fan speed in both cooling and heating modes, helping provide even air distribution across larger homes and multiple rooms.

Single-Phase Power Supply

This model operates on standard 230V single-phase power, making it suitable for most residential properties without requiring 3-phase electrical upgrades.

Energy Efficient Performance

The system delivers an EER of approximately 3.29 and a COP of 4.09, helping reduce ongoing running costs while maintaining strong heating and cooling performance. Fujitsu’s R32 high static range is designed to improve efficiency while still providing strong airflow performance.

Compact Indoor Unit Design

The indoor unit measures approximately 425mm high, 1250mm wide, and 490mm deep, while the outdoor unit measures approximately 998mm high, 940mm wide, and 320mm deep. Despite its high static capability, the system remains compact enough for a wide range of roof space installations.

Quiet Operation

Indoor sound levels are approximately 43dBA on high fan speed and as low as 35dBA on quiet mode. Outdoor sound pressure levels are approximately 55dBA in cooling mode and 57dBA in heating mode, helping maintain quieter day-to-day performance.

R32 Refrigerant

The system uses modern R32 refrigerant, which provides improved efficiency and a significantly lower global warming potential than older refrigerants such as R410A. Fujitsu notes that R32 systems are designed to reduce environmental impact while maintaining strong performance.

Wide Operating Range

The unit can operate in outdoor temperatures up to 50°C in cooling mode, making it suitable for harsh Australian summer conditions and year-round performance.

Zone Control Compatible

The High Static Single Phase R32 range is zone control compatible, allowing users to independently manage airflow to different areas of the home for improved comfort and energy savings.

Demand Response Ready

The system supports demand response programs, allowing the unit to reduce energy usage when required by electricity providers. It also includes features such as auto restart and auto changeover.

UTY-RNRT Touch Controller Included

This system includes the Fujitsu UTY-RNRT LCD touch panel controller for simple temperature adjustment, operating modes, scheduling, and zone control integration. Optional Wi-Fi control is also available through Fujitsu anywAiR® technology.
